GERMANY PRODUCTION OF WALL PROTECTIVE MEANS Application filed July 8, 1930, Serial No.

,The invention relates to an improvement in the production of wall protective means against premature destruction, which serve essentially for protecting walls, and more especially the corners of walls which are more excessively exposed to the influences of weather. Attempts have hitherto been made to remove the drawback of premature destruction of the masonry and wall corners by various means, but without success. Amongst other things use has been made of waterproof substances, for instance linen imre ated with mag nes iafluate SW terial, provided with a coating 6f oilpaint in various intermediate layers, which material has been worked up with the masonry, in which cases attempts were made to protect or reinforce the plaster of the outer edge surfaces and wall cor'ners by embedding fabrics. U However all these devices have proved to lack durability and were unable to withstand premature destruction.

It is however possible by the present invention to obtain a reliable protection where- 85 by mainly the wall edges and other wall surfaces greatly exposed to weather are well protected.

The method is as follows: A moist, fine-meshed strip of linen is passed 80 between two heated rollers, the surfaces of which are serrated or roughened in such a way that they can penetrate into the fine meshes of a strip of linen from both sides. By this means the mesh openings have been 85 widened and given a peculiar shape on both sides and the mesh strands are reinforced, whereby the entire fabricsis consolidated in structure, without affecting its flexibility. After leaving the rollers the strip of linen 0 which is now dry, is passed in its entire length into a receptacle which contains a composition prepared preferably from glgg, carbo liggcjd potassium dichromate, water- 'glass, caoutc one and rockliln'ein suitable proportions and mixed'i'iiin intermediate process. This mass fills up the meshes of the linen strip, which have been given a peculiar shape by the rolling operation, in such a way that after the application or fixing of I" the linen strip prepared in this manner this 466,601, and in Germany July 26, 1929.

mass adheres to the masonry and indissolubly unites with the same by suitable wall plaster, that is to say even after the plaster falls off, said mass still offers a reliable security for the protection of the wall, as it cannot drop out of the meshes or the fabric.

The following is an example of preparing a suitable composition p About 6 kilos of fine lue are soaked in about 4 liters of water and after 48 hours boiled in a vat. hereupon this mixture is cooled with about 10 liters cold water.

Separately from this mixture, the following ingredients are mixed, namely 250 grs. of

otassium dichromate (sioakedl in one liter and 0,3 liter water lass an 0,5 'ter caoutchouc with a kilo of black carbolic acid.

s mass thus produce 18 en mixe W1 the cooled mixture referred to above. Thereupon are mixed separately, 3 kilos rock lime in about 2 liters of cold water, wmn united with the afd'fineiifibned mixture, then gives the finished composition, with which the linen is impregnated and applied to the masonry.

The accompanying drawing shows in diagrammatic form on a considerably enlarged scale wherein Fig. 1 indicates in section the shape of the meshes of the linen strip after passing through the serrated rollers, and Fig. 2 shows the mesh filled with impregnation mass. For the sake of clearness only one original and one re-shaped mesh is shown in each case.

In the drawing, a is the re-shaped mesh of the fabric, (1 is the impregnating mass, and g is the linen strip filled with the im-' pregnating mass (1, see Fig. 2.

I claim: I

1. A method of producing a wall protecting means of impregnated smooth-faced textile fabric to be imbedded in the wall laster, which method consists in providing om both sides and in the entire length of the fabric, truncated widenings of its meshes, in order to increase the strength and filling said widened meshes with a composition consisting of the followin ingredients namely glue, black carbolic aci waterglass, caoutchouc and rock lime.

2. A method of producing a wall protectpotassium dichromate, I

mg means as described in claim 1, in which said filling com osition is obtained by soaking 6 kilos of ne glue in 4 liters of water and boiling up after 48 hours, thereupon cooling with 10 liters of cold water and 'adding to a mass prepared separately and composed of 1 kilo of black carbolic acid, 250 grs. potassium dichromate soaked in 1 liter, 0.3 liter of waterglass and 0.5 caoutchouc, whereupon a mixture, prepared separatel of two liters of cold water and 3 kilos roc lime is united with the foregoin mixture.

In testimony whereof aifix my signature.
